Abstract

Dispersion maps of antipodal symmetric type for improvement of compensation effect in dispersion managed link combined with optical phase conjugation, which can compensate for the distorted wavelength division multiplexed (WDM) signals due to chromatic dispersion and nonlinear Kerr effects of single-mode fiber, were proposed. It was confirmed that the proposed all of antipodal symmetric dispersion maps was more effective to compensate for the distorted WDM channels than the conventional link of uniform type dispersion map. Especially, dispersion maps formed like the inversion of alphabet S were more advantageous as the distorted WDM channels were compensated than dispersion maps formed like alphabet S. It was expected that the variety of optical network topology was more expanded by applying the proposed antipodal symmetric dispersion maps into transmission link.

단일 모드 광섬유의 본질적인 색 분산과 비선형 Kerr 효과에 의해 왜곡되는 파장 분할 다중 신호의 보상을 위한 광 위상 공액기를 갖는 분산 제어 링크에서의 보상 효과 제고를 위한 원점 대칭 구조의 분산 맵을 제안하였다. 제안된 모든 형태의 원점 대칭 분산맵을 갖는 분산 제어 링크는 전통적인 균일 구조의 분산 제어 링크에 비해 파장 분할 다중 채널의 왜곡 보상에 효과적이라는 것을 확인하였다. 특히 알파벳 S자 형태의 분산 맵보다 알파벳 S자를 상하 반전시킨 형태인 분산 맵의 구조를 다양한 형태로 변형시켜도 왜곡 보상에 유리하다는 것을 확인하였다. 제안된 원점 대칭 구조의 분산 맵을 전송 링크에 적용하면 광 네트워크의 토폴로지를 보다 다양하게 구성할 수 있을 것으로 기대된다.
